BRAKE COMPANY,

` BRAKE OIL GUARD.

' 'A pplicaton led November '28, 1924. Serial No. 752,567'.

Therobjectof'thi's invention is to provide Ineans for preventing lubricant, used foi` lubricating thewheel bearings of a vehicle,

- such-.as-an automobile, from reaching the shoes.

braking surfaces, face of the' flange Numerous devices, such comprising the inner surf of the drum and the brake as felt washers,` have been and are in use at the gpresent timeto prevent' the lubricant from creeping outyof the wheelhubs. along the head wall of thefbra'ke 'drurnand reaching 'centrifugal gravity forces.

I. .the said braking surfacesthrough t he effect It vis clearly understoodthat when, this lubricant reach-es the .braking surfaces, particularlg, ll e quantity, the braking effect' wi `reduced with obvious results.

.It is the object of my invention to' provide 1n 'surfaces refere positive means,

reventing lubrl invention 'win tje-sf* tel 'understood by nce to the following speciiicatiomtaken "11'1v vconnection with the' annexeddrawmg,

in any greatly of a very simple nature, for cant from reaching th.e'brak" a" muchv reduced scale' showing a conventional form of front wheel vehicle hub and attached. to the hub disc wheel. The brake drum 4and o beingshown attached tO the hub an Figure 2 is a sectional view 0f a of oil guard assembled thereto.-

Referring now to the details Whe numbers refer to various views, portions 2 and on the spindle 1 by and as usual vthe cavity 7 is packed with grease with its bearings, a portion of the.

for .p off showing illustrated in. Fig. 2, may Y e itis fastened 555 Vof form of'4 rein like corresponding parts in their 1 'is' a wheel 'spindlehaving 3 for mounting on the vehicle bearings practice, and 1n divert this lubric the drum 1, suchl the'drum, it is to be in the shape of a.

tion of vthe packing washer 9, or its equivalent, more or less lubricant gets out of the chamber 7, particularly, in hot weather, then, this lubricant is thrown onto ythe'braking surface 10 by the brake drumv 1 1 and Onto the brake shoes, whichare not shown. To

-12 has a seriesof holes 16 therethrough about on a line with the web of the oil guard, so as to get the maximum effect of centrifugal force to 'drive the lubricant out through the holes 16. vT hese holes arein alignment'with correspondin holes through the drum 11 so that asthe lu drum. uard 17 1s circular 1n form, the same as 1n the Oil guard isshown as riveted a series of' rivets/*18 to the drum 1. It is t be understoodthat'other means may be provided for fastening the Oil guard 17 to as fspot or line ywelding.

ant from the braking sur. faces, I have provided an-annular member which flange' rieant is caught by'the channel it is'forced through the holes, `16to the points exterior of the In. Fig. 2, the oil ig'. 1, and hasa central opening for the. wheelspindle.` Near its outer S- periphery, Y

In this construction holes 16 are placed near'4 -fthe pointof. attachment of the member 17,

tothe drum 1.-'Whe1`1 rivets ortheir equivalent are used for fastening the oil guard to understoodthat paint or the like may be use to assist in making the'jointy between the guard and drum, oil tight.

In Fig. 3 the oil vguard is'shown somewhat dish; In both Figs. 2 and 3 the edge 19 of the oil guard 17 may be turned over in-order to stiifen the edge thereby assisting in gettin an oil tight joint where the oil uard 17 1s attached to the drum. It isto'v e understood that the holes 16, in each'v construction shown, are so positioned'ns understood'that sucient number are-used so to clear all obstructions so as to insure the carrying away of indicated at inl Figs. 4 recesses for collecting assist in .feeding the lubricant to the holes 16.

In lig.v 6 a section of the what triangular in-shape, modifications merely indicate 'how the details oil g-uard is somefor carrying -my-invention into practise may be varied; consequently,

guard 17 through the drum to be engaged by Ido not wish to be. unduly limited in the interpretation thereof.

Fig. 7 a drum 10 is carried on the Wheel spindle 1 and the oil guard 17, is similar to that shown in Fig. 2,. except the cone of the'- guard has a greater angle and preferably, the plane 21 of the end of the lcone extends beyond the plane 22 of the hub; the portion 23 having a curvature as large as possible to insure the diversion of the lubricant by the holes 16.

' lHaving thus described my invention what I claim is:

1. In a vehicle wheel equipped with a brake drum to be engaged by brake members, means from the braking surfaces of the drum and brake members comprising; a'plate, preferably-circular in shape, having a central spindle opening and being fastened near its periphery to the drum, said" drum having-holes therein near the line of attachment of the plate to the drum, while said plate is so formed as to catch lubricant leaking intothe drum and carry it to the said 2. In a vehicle wheel equipped with abrake drum to be engaged by brake members7 means for diverting lubricant from the brakingvsurfaces of the drum .and brake members comprising, a plate, preferably circular in shape, having a central spindle opening and being fastened near its periphery to the drum, said drum having holes therein near theV line of attachment ofthe plate to the drum, said plate 'having a portion formed away from the drum so as to catch lubricant leaking from the wheel bearings.

3. yIn a vehicle wheel equipped with a brake brake members, means for diverting lubricant from the braking surfaces of the drumy and brake members butthese various.

comprising; a plate, preferably circular in shape, havingV a central spindle opening and being fastened near its periphery to the drum, said drumhaving holes therein near the line of attachment of the plate to the drum, said plate having its edge turned over on a line more distant from the center of thc Wheel than said line of attachmentso as to stiften the plate and to insure the catching of lubricant leaking into the drum and for carrying it to said drain holes in the drum.

4. In a vehiclel wheel equipped with a brake drum to be engaged by brake members, means for diverting lubricant from the braking surfaces of the drum and brake members comprising insaid drum, a series of holes prefer-ably spaced equidistant from the ccnter of the Wheel and a plate preferably circular formed and fastened to the drum in such a manner as to catch lubricant leaking into the drum and divert itfto said series of holes'.

5. In a vehicle wheel equipped with a brake drum to be engaged by brake members, means for diverting lubricant from the braking surfaces of the drum and brake -members comprising a circular stamped metal member channel shaped in cross section, one flange of the channel being wider than the other and fastened to the Wheel and drum, said channel shaped member having a series of holes through the wide flange just above the web of the member while said drum has a series of holes in alignment with the holes in the channel member.

6. A wheel having a brake drum, in combination with a guard for conveyinglubricant outside of the drum, and common means for securing the guard to the drum and the drum to the Wheel.

7. A wheel having a brake drum, in combination with a guard for conveying lubricant outside of the drum and common fastenings .passing through the guard and drum and 'securing them together and securing them both to the wheel. i

8. A wheel having a brake drum, in combination with a lubricant guard carriedby the drum and formed with discharge openings and radial grooves cant to the openings.

In testimony whereof I affix my signature.
